It’s important to keep your furnace receives regular maintenance to ensure that it’s working properly and efficiently. Routine maintenance can also extend the life of your heating system by several years. Ask about our annual maintenance agreements that cover your plumbing, heating, and cooling systems and save you money. A furnace that has been neglected may be working too hard, which can result in inconsistent air temperatures in your Minneapolis area home.

Gas furnaces and heaters have control shutoffs to prevent gas leaks, but they are not fail-safe. If you smell gas in your house, do not turn any lights on or off, and do not try to shut off the gas leading to the furnace. Get out of the house, leaving the door open, and immediately call the gas company or the fire department to report a leak. Do not re-enter your home.

American Standard manufactures and markets central furnaces that are available in single and multistage configurations, with some models capable of an AFUE rating of more than 90 percent. American Standard markets units that meet Energy Star requirements and makes others that it claims offer quiet operation. The average price of an American Standard central gas furnace is about $3,000 and American Standards are sold through their dealer network.
Appointment was scheduled between 8am and 11 am, technician called and said that he will at 11 am, technician arrived at 11:23am. The request for service was regarding Furnace Maintenance, more specifically fan won't stop turning after heater has stopped after reaching desired temperature. Service was provide by Sam Singh from WesternAir Mechanical Heating & Air Conditioning. The mechanic opened the side panels of the heater+ac unit and concluded that the unit is too old for maintenance, as in it is not worth it, even though I have already payed $94.19 through Amazon.com. The mechanic spend close to one hour explaining how my heater+ac unit is too old for any updates and that it should just be replaced. I didn't receive any of the services that are included in the Furnace Maintenance package listed on Amazon.com. https://www.amazon.com/gp/product/B015JRGSQI/ref=od_aui_detailpages00?ie=UTF8&psc=1 I was ripped off my this company and I would very much like my money to be returned to me. Opening and closing the panels of my unit doesn't cost more than $2, I can do that by myself.
Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.

High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
